IQuoter

Quoter Interface Supports quoting the calculated amounts from exact input or exact output swaps Developer note: These functions are not marked view because they rely on calling non-view functions and reverting to compute the result. They are also not gas efficient and should not be called on-chain.

Functions

quoteExactInput

quoteExactInput(bytes,uint256) external

Returns the amount out received for a given exact input swap without executing the swap

Name	Type	Description
path	bytes	The path of the swap, i.e. each token pair
amountIn	uint256	The amount of the first token to swap

Returns:

Name	Type	Description
amountOut	uint256
fees	uint16[]

quoteExactInputSingle

quoteExactInputSingle(address,address,uint256,uint160) external

Returns the amount out received for a given exact input but for a swap of a single pool

Name	Type	Description
tokenIn	address	The token being swapped in
tokenOut	address	The token being swapped out
amountIn	uint256	The desired input amount
limitSqrtPrice	uint160	The price limit of the pool that cannot be exceeded by the swap

Returns:

Name	Type	Description
amountOut	uint256
fee	uint16

quoteExactOutput

quoteExactOutput(bytes,uint256) external

Returns the amount in required for a given exact output swap without executing the swap

Name	Type	Description
path	bytes	The path of the swap, i.e. each token pair. Path must be provided in reverse order
amountOut	uint256	The amount of the last token to receive

Returns:

Name	Type	Description
amountIn	uint256
fees	uint16[]

quoteExactOutputSingle

quoteExactOutputSingle(address,address,uint256,uint160) external

Returns the amount in required to receive the given exact output amount but for a swap of a single pool

Name	Type	Description
tokenIn	address	The token being swapped in
tokenOut	address	The token being swapped out
amountOut	uint256	The desired output amount
limitSqrtPrice	uint160	The price limit of the pool that cannot be exceeded by the swap

Returns:

Name	Type	Description
